However, combining a Haspin inhibitor (CHR-6494) with alisertib reduced cell viability favorably and inhibited its in vivo and in vitro tumor growth by causing extreme microtubule depolymerization, and along with other mechanisms, the mitotic process was disrupted, brought forth by the obliteration of the recruitment of Aurora-B and mitotic centromere associated kinesin to the centromeres. This evidence concerns the gene KIF2C and neoplasm.
